' The embodiment shown in Figs. 1 to includes a handle 1 which may have a' screw threaded connection with a member 2 secured in any suitable manner to the main frame 3 of the razor head, which maybe of the general-shape indicated in Figs. 2 and 4, and have formed integral therewith guards 4 and 5 constructed as shown to provide guard teeth. It is obvious, of course, that these guard teeth may be formed in any suitable manner andthat as to certain ects teeth-ma be omitted andda continuous. guard mem r 'llsed instea w v The guards rand-5 may be dispose" 'd at. right angles to the upper part 6 of t e 'de-wayv frame 3 to recelve a (guide-way 7 or the ,7.may be ma integral with or ormed on the member 6 in any suitable manner. Slidable on the ideway 7 and retained therein by overhangmg flanges on the g'uide-way is a slide plate 8 in w ich are secured s acer .studs9 and on which is supporte the inner clamping member 11 to which is clamped a razor blade 12 by an outer clamping member or .cap plate 13-.

Threadedly engaging'the slpaoer studs 9- ampmg mem and 10 and securing the inner c ahning pins 14 and which extend through the razor blade 12 and the outer cap plate 13 and are provided 'with'screw driver engaging slots for facilitatin their connection with and disconnection rom the spacers 9 and 10. The sides of the alining pins may be shaped as shown in Fig. 3 to conform to the slot in a razor blade of standard make, the blade functioning in this instance to lock the alining pins 14 and 15 in the position in which they'clamp the inner clamping member 11 on the spacer studs 9 and 10.

The cap plate or outer clamping member 13 may be provided with a short screw threaded member 16 with which cooperates a threaded member 17 having an enlarged portion resting on the slide 8 which also acts as a spacer member and having1 a reduced portion projecting through a ole in the-slide 8 and slots in the guide-way 7 and the upper part 6 of the frame 3. The free end of the member 17 may be provided with a thumb wheel 18, as shown. By turning the thumb wheel 18 the cap plate may be drawn I inwardly toward the inner clamping memher to secure the razor blade and to move it against the guards 4 and 5 under any desired pressure for cooperation with the guards during the operation of the sharpening, as shown in Figs. 4 and 5, or to permit the withdrawal of the edges of the razor blade into any desired suitable shaving position, as shown in Fig. 1.

The spacer stud 10, as shown in Fig. 2, may be provided with a recess into which projects the wedge-shaped end of a bolt 20 which has a threaded connection with a member 21 supported in the frame member 3 and which may be turned and advanced by means of a thumb wheel 22 into the position shown in Fig. 2 in which it looks the slide 8, the clamping members and" the razor blade in the position in which these parts occupy during shaving.

By withdrawing the bolt 20 from the recess in the spacer stud 10 into the position shown in Fig. 4 the slide 8 and all the parts carried thereby are free to be moved back and forth in the guide-way 7 whereby, when the edges of the blade are drawn against the guards as shown in Fig. 5, the lower faces of the opposite edges of the razor blade will be sharpened. The opposite faces of the edges of t e razor blade may be sharpened after the blade has been reversed in the clamping members and the parts are again brought into the position shown in Fig. 5. The pressure of the razor blade on the uards may be adjusted by means of the thum% wheel 18.

After the sharpening operation has been completed the slide 8 is rought into the position shown in Fig. 2 and is locked in this position by advancing the bolt 20, after which the thumb wheel 18 may be turned to space the edges of the razor blade from the guards 4 and 5, as shown in Fig. 1.

The modification shown in Figs. 6 to 17 includes a handle 21 which has a reduced portion 22 adjustable in a member 23 secured bers are moved out of shaving position. The

construction is such also that when the guard members are moved into the shaving position shown in Figs. 11 and 13 they ma cause the honing members to move into fiilly withdrawn position. The movement of the honing members from the honing position shown in Fig. 12 upon release by movement of the guard members into shaving position is initiated by a spring 39, Fig. 16, coiled about a rod 40 and having its ends bearing against the honing plates 37 and 38. The plates 37 and 38 are provided with eyes through which the rod 40 extends. The rod 40 is supported in upstanding cars 41 and 42 on the frame 24. The guard members may be provided with cam-shaped raised portions 43 and 44 coopcrating-with the free ends'of a plate s ring 45 secured to the bottom face of the rame member 24 to hold the guard members in either of the positions indicated in Figs. 11 and 12 and Figs. 13 and 14.

For the purpose of slidably supporting the razor blade and clamping mechanism on the frame member 24 a guide-way 46 may be secured to the frame member 24, the guide-way being formed as in the first modification and being adapted to receive and cooperate with the base 47 of a razor carriage 48, Fig. 10, the ends of the base being recessed, as shown in Fig. 10, to avoid interference with the ears 41 and 42 on the frame 24. The carriage 48 may be provided with a razor blade supporting member 49 which constitutes the inner clamping member for the razor blade 50. The ends of the plate or supporting member 49 may be provided with finger pieces 51 and 52 by means of which the carriage 48 may he slid back and forth in guide-way 46. The finger pieces 51 and 52 also constitute abutments for the ends ofthe razor blade 50 as clearly indicated in Figs. 9 and 15. The plate 49 may be provided with alining studs 53 and 54 which pass through'a slot or the equivalent in the blade 50 and are enlarged to form seats for the outer clamping plate or cap member 55 which is provided with bayonet slots for connection under the heads of studs 53 and 54, as clearly indicated. The right hand endof the cap plate 55 is recessed to clear the ear 51.

The base member 47 of the carriage is provided with a recess into which the end 56 of the reduced portion 22 of the handle 21 may extend to lock the carri ge 48 in the position shown in Fig. 9.

' ,When the carriage 48'is in the position indicated in Fig. 9, and the guards and honing members are 11 and 13, the razor is in condition for a shaving operation. When it is desired to hone the razor the guards are'swung away from the edges of the razor blades into the position shown in Figs. 12 and 14 which causes the honing members 37. and 38 to be moved into cooperative relation with the edges of the razor blade for honin as shown in these figures. The end 56 of the reduced portion 15 22 of the handle 21 is withdrawn by a counter-clockwise rotation of the handle, into the position shown in Figs. 14 and 15, so that the carriage 48 and the parts carried thereby may be moved back and forth to cause the edges 'tudinally of the honing plates, as indicated y the position of the parts shown in Fig. 15. After the honing operation has been completed the carriage 48 is centered with respect to the frame 24 and the end of the handle is advanced from the position shown in Fig. 15

to the position shown in Figs. 9 and 1 3 to lock the carriage 48 and the parts carried thereby in shaving position.

While the invention has been described with particular reference tothe embodiments disclosed, it is obvious that the invention may 20 of the razor blade to move back and forth 1on take other forms or embodiments, and it is to be understood that the words used in the claims are words of description and not of limitation.
